Neurotrophic factors (NTFs) are small secreted proteins that support the development, maturation and survival of neurons. NTFs injected into brain rescue regenerate certain neuronal populations lost in neurodegenerative diseases, demonstrating potential to cure diseases rather than simply alleviating symptoms. (as vast majority molecules) do not pass through blood–brain barrier (BBB) therefore, delivered directly patients using costly risky intracranial surgery. The delivery efficacy poor diffusion some inside considered major problems behind their modest effects clinical trials. Thus, there is a great need for be systemically thereby avoiding Nanoparticles (NPs), particles with size dimensions 1-100 nm, can used stabilize facilitate transport BBB. Several studies have shown loaded or attached onto NPs, administered transported brain. To improve NP-mediated NTF BBB, surface NPs functionalized specific ligands such as transferrin, insulin, lactoferrin, apolipoproteins, antibodies short peptides will recognized internalized by respective receptors on endothelial cells. In this review, we elaborate most suitable methods envision “ideal” Parkinson’s disease (PD) trial thereof. We shortly summarize trials four NTFs, glial cell line-derived neurotrophic factor (GDNF), neurturin (NRTN), platelet-derived growth (PDGF-BB), cerebral dopamine (CDNF), were tested PD patients, focusing mainly GDNF CDNF. current possibilities discuss whether impact improving properties across Emerging approaches future directions NTF-based nanomedicine also discussed.

Major depressive disorder (MDD) is a devastating psychiatric which exacts enormous personal and social-economic burdens. Ketamine, an N -methyl-D-aspartate receptor (NMDAR) antagonist, has been discovered to exert rapid sustained antidepressant-like actions on MDD patients animal models. However, the dissociation psychotomimetic propensities of ketamine have limited its use for indications. Here, we review recently proposed mechanistic hypotheses regarding how exerts actions. Ketamine may potentiate α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPAR)-mediated transmission in pyramidal neurons by disinhibition and/or blockade spontaneous NMDAR-mediated neurotransmission. also activate neuroplasticity- synaptogenesis-relevant signaling pathways, converge key components like brain-derived neurotrophic factor (BDNF)/tropomyosin kinase B (TrkB) target rapamycin (mTOR). These processes subsequently rebalance excitatory/inhibitory restore neural network integrity that compromised depression. Understanding mechanisms underpinning ketamine’s at cellular circuit level will drive development safe effective pharmacological interventions treatment MDD.
